Computer Addresses

For the sake of this tutorial, drawings of memory are shown in the form of a ribbon divided into boxes. Each box represents a single byte with its own address. The sample addresses shown in the drawings run from 924 to 940.

Many of the sample programs in this tutorial will print addresses to the screen. Typically, the address values shown when running these programs will be quite high. It isn't unusual to see something like 3221223612 displayed for an address.

Don't worry that the addresses you see when running the sample programs are much larger than those shown in the drawings. Small 3 digit addresses are used in the drawings because it is much easier on the eyes than trying to read 10 digit addresses underneath each byte of memory.
